--- Comment #51 from [email protected] --- AI generated via ChatGPT 2026-08-05 I can confirm this issue is still present with current LibreOffice releases. **System** * Hardware: ASUS ZenBook UX303LB with Atmel touchscreen (10-touch) * OS: Linux Mint 22.3 Cinnamon * Kernel: 6.17.0-35-generic * LibreOffice: 26.2.5.2 (Ubuntu package `4:26.2.5.2-0ubuntu0.24.04.1~lo1`) * VCL: gtk3 * UI render: default **Testing performed** The touchscreen hardware and input stack have been verified to be working correctly: * `xinput` detects the Atmel touchscreen. * `xinput test-xi2` reports normal `RawTouchBegin`, `RawTouchUpdate`, and `RawTouchEnd` events while dragging a finger on the screen. * `libinput` is in use. * The issue occurs with both: * Cinnamon (X11) * Cinnamon Wayland (Experimental) I also tested different LibreOffice VCL backends: * `SAL_USE_VCLPLUGIN=gtk3` → no touchscreen scrolling * `SAL_USE_VCLPLUGIN=qt6` → no touchscreen scrolling * `SAL_USE_VCLPLUGIN=gen` → no touchscreen scrolling **Comparison with other applications** On the same system and using the same touchscreen: * Brave: touchscreen scrolling works. * Firefox: touchscreen scrolling works under Wayland. * Thunderbird: touchscreen scrolling works under Wayland. * LibreOffice Writer: touchscreen drag does not scroll the document. This suggests the touchscreen hardware, kernel, libinput, and Wayland/X11 input stack are functioning correctly, and the remaining issue is specific to LibreOffice's handling of touchscreen scrolling events. other GTK applications work correctly on the same system In the same Wayland session, Firefox, Thunderbird and Brave all support touchscreen scrolling correctly. This indicates the touchscreen hardware, libinput and Wayland input stack are functioning normally, and the issue appears to be specific to LibreOffice. -- You are receiving this mail because: You are the assignee for the bug.
